Abstract:The functional mechanisms of probiotics were analyzed in this paper, and the efficacies of several common aquatic feed probiotics were described such as providing nutrition to promote growth; enhancing immunity of animals to prevent from diseases; decomposing organic pollutants to purify water quality and improve ecological environment. Then some problems existed currently had been presented and the prospects had also been discussed, that would be of important significance for a better application of probiotics in aquaculture in future.

在水产养殖过程中由于大量投喂饲料,造成水体中残余饲料、水产动物的排泄物及残骸大量积累,细菌繁殖几率增加,导致水质变差,水产病害时有发生。虽然抗生素及化学药物可缓解细菌繁殖及水产病害问题,但过量使用会引致一系列相应的问题,如养殖产品抗生素超标将破坏水产动物肠道内菌群的结构,使动物...
